The GED (General Educational Development) test is a vital pathway for individuals to earn a high school equivalency credential. For many test-takers, the mathematics section can be a significant hurdle. Understanding the tools available to assist with calculations is crucial for success, and this includes knowing precisely which calculators are permitted. The GED test designers have specific regulations in place to ensure a standardized and fair testing environment, and these regulations extend to the approved calculator policy. This article will delve into the specifics of what calculator is allowed on the GED, providing clarity and guidance for all aspiring GED candidates.
The Official GED Calculator Policy
The GED Testing Service is the official administrator of the GED test, and they dictate the policies surrounding approved calculators. Their primary objective is to ensure that the test assesses a candidate’s mathematical understanding and problem-solving skills, rather than their proficiency with advanced calculator functions. This means that the approved calculators are generally simpler and designed to assist with basic to intermediate calculations.
Understanding the “Calculator Allowed” Sections
The GED test is divided into four subtests: Mathematical Reasoning, Science, Social Studies, and Reasoning Through Language Arts. The calculator policy primarily impacts the Mathematical Reasoning subtest. However, it’s important to note that the GED computer interface itself includes a built-in calculator for most questions.
The On-Screen Calculator
For the majority of the Mathematical Reasoning subtest, candidates will utilize an on-screen calculator provided within the testing software. This calculator is designed to be straightforward and functional, mimicking a basic calculator. It typically includes standard arithmetic operations (addition, subtraction, multiplication, division), percentage calculations, and a square root function. The interface is usually intuitive, allowing test-takers to input numbers and operations directly using their mouse or keyboard.
This on-screen calculator is a critical component of the GED experience and is available for almost all mathematical reasoning questions. This standardization ensures that every test-taker has access to the same computational aid, leveling the playing field and focusing the assessment on their mathematical comprehension and application.
When a Handheld Calculator is Permitted
There are specific instances where a personal calculator is allowed on the GED, though these are less common and subject to strict guidelines. These instances are typically tied to the Mathematical Reasoning test’s structure and question types.
The Calculator-Active Section
The GED Mathematical Reasoning test is structured into two parts. The first part typically prohibits the use of any calculator, requiring candidates to perform calculations manually. The second part of the Mathematical Reasoning test, however, does allow for the use of a calculator. This is where the distinction between the on-screen calculator and a permitted handheld calculator becomes relevant.
When a handheld calculator is permitted, it is usually the Texas Instruments TI-30XS MultiView Scientific Calculator. This specific model has been chosen by the GED Testing Service due to its balance of functionality and its ability to prevent undue advantage.
Approved Handheld Calculators: The TI-30XS MultiView
The Texas Instruments TI-30XS MultiView Scientific Calculator is the gold standard for handheld calculators permitted on the GED exam. Its selection is not arbitrary; it’s based on its capabilities aligning with the mathematical concepts assessed in the GED, while also avoiding functions that could trivialize the test’s purpose.
Why the TI-30XS MultiView?
The TI-30XS MultiView is a scientific calculator that offers a good range of functions without venturing into the territory of advanced graphing or programming capabilities, which are generally deemed too complex for the GED’s assessment goals.

What Makes it “Allowed” and Others “Not Allowed”?
The GED Testing Service’s approval of the TI-30XS MultiView is based on a deliberate policy to prevent candidates from gaining an unfair advantage. Calculators with more advanced features, such as graphing capabilities, programmability, or the ability to store extensive text or formulas, are generally prohibited.
Prohibited Calculator Features
- Graphing Capabilities: Calculators that can plot graphs of functions are not allowed. These are considered too powerful for the GED’s assessment of fundamental mathematical reasoning.
- Programmability: Calculators that allow users to write and store programs are also forbidden. This could be used to pre-program solutions or shortcuts, undermining the test’s intent.
- Text Storage: Any calculator capable of storing text or formulas is disallowed.
- Communication Devices: Calculators that can communicate wirelessly with other devices or access the internet are strictly forbidden.
- Large Displays: While the TI-30XS has a multi-view display, excessively large screens that could display extensive information or be used for other purposes might be restricted.
The GED Testing Service aims for a balance. They want to provide a tool that aids in computation but doesn’t provide answers or bypass the need for understanding mathematical concepts. The TI-30XS MultiView strikes this balance effectively.
